Side of square= 2*24=48

Perimeter= 4*48= 192in.

7.Base angles of both triangles are 51 and 90.

So, triangles are similar by AA similarity theorem.

Answer:

11a.  m <1 = 131          12a.  m <1 = 42

11b.  m <2 = 49          12b.  m <3 = 75

11c.  m <3 = 131          12c.  m <4 = 42

11d.  m <4 = 49          12d.  m <5 = 63

11e.  m <5 = 131         12e.  m <6 = 75

11f.  m <6 = 49          12f.  m <7 = 105

11g.  m <8 = 49          12g.  m <8 = 75

11h.  m <9 = 92          12h.  m <10 = 75

11i.  m <10 = 88          12i.  m <11 = 42

11j.  m <11 = 92          12j.  m <12 = 138

11k.  m <12 = 88         12k.  m <13 = 42

11l.  m <13 = 92         12l.  m <14 = 138

11m. m <14 = 88

11n.  m <15 = 92

Step-by-step explanation:

When lines are parallel to  each other than:

Corresponding Angles are equal.

Alternate Interior Angles are equal.

Alternate Exterior Angles are equal.

Consecutive Interior Angles add up to 180 degrees.

You can check some math websites for definitions of these angle relationships.

The steps below show the incomplete solution to find the value of m for the equation 5m − 2m + 4 = −1 + 12: Step 1: 5m − 2m + 3
Delicious77 [7]

Given:

Consider the equation is:

5m-2m+3=-1+12

Some steps of the solution are given.

To find:

The next step of the solution.

Solution:

Step 1: The given equation is:

5m-2m+3=-1+12

Step 2: Simplifying right hand side.

5m-2m+3=11

Step 3: Simplifying left hand side.

3m+3=11

These steps are already given. So, the next step is:

Step 4: Subtracting 3 from both sides.

3m=8

Therefore, the correct option is (b).

VARVARA [1.3K]

Answer:

Erin gets £90

Step-by-step explanation:

Ratio = 5 : 2 : 7

Money with Erin = 5x

Money with Faye = 2x

Money with Sachin = 7x

Faye gets £90 less than Sachin

7x -  2x = 90

      5x = 90

        x = 90/5

        x = 18

Money with Erin = 5*18 = 90
